OGRE 1.11.5 Working on ‘Phosphene’

One of the open-source software projects which has often fascinated me, is called OGRE, which stands for Open-Source Graphics Rendering Engine. It’s a very powerful set of libraries, that allows good coders to design 3D graphics applications, which take full advantage of hardware-accelerated – i.e., GPU-based – rendering, of virtual 3D scenes designed by such users, into simulated 2D camera views, within the same scene. This is one of the most common modes in which 3D Graphics is operated.

One of the things that OGRE is not, is a full-fledged game engine unto itself. This is due to:

  • Lack of sound implementation (Additionally linking applications to the SDL Library may solve that),
  • Lack of scripting support, without some sort of add-on. I think I compiled it with Python support, which would supply scripting, if my coding was good enough.

Modern builds of OGRE break with the past, in that they no longer use ‘OIS’ as their input system. Instead, at least their Sample Browser uses the ‘SDL library’ to do the same.

One of the feats which I have now accomplished on the computer named ‘Phosphene’, which is a Debian / Stretch, Debian 9 system, was to compile version 1.11.5 of this engine because I’m curious about Game Design, which I have been for a long time. And one of the reasons I feel that this software is stable on Phosphene, is due to the information which I already provided in This past posting. The past posting announced observations which I made, when this same hardware was called the computer ‘Plato’, but already running Debian Stretch.

What my observation essentially suggests is, that running 3D, OpenGL applications can in fact break the compositor because they suspend it, but that there is a work-around.
